The shell is a lightweight denim, very soft, looks like a rich indigo chambray. Lined in the upper half with a rayon/poly blend and a gauzy cotton on the bottom. 3 buttons, no vent, button-back collar closure (see photos). I've included a professional photo as well for a fit pic. For more professional photos see here:

20.25 inches from armpit to armpit
18 inches from shoulder seam to shoulder seam
25 inches from shoulder seam to sleeve end
28.5 inches from bottom of collar to bottom of garment

All prices listed here include shipping when shipped to an address in the continental U.S. If you live outside the U.S., let me know and I'll give you a revised quote.Edited by xander_horst - 5/5/13 at 5:04pm
